Injective MCP Server

An MCP (Model Context Protocol) server that gives AI agents full trading capabilities on Injective — perpetual futures, spot transfers, cross-chain bridging, and raw EVM transactions.

Connect it to Claude Desktop or Claude Code and trade with natural language.

Read-only. | | bridge_debridge_send | Bridge tokens from Injective to another chain via deBridge DLN. |

EVM

| Tool | Description | |---|---| | evm_broadcast | Broadcast a raw EVM transaction on Injective EVM. |

Setup

npm install
npm run build

Connect to Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "injective": {
      "command": "node",
      "args": ["/path/to/mcp-server/dist/mcp/server.js"],
      "env": {
        "INJECTIVE_NETWORK": "mainnet"
      }
    }
  }
}

Connect to Claude Code

Add to ~/.claude/mcp.json or your project's MCP config:

{
  "mcpServers": {
    "injective": {
      "command": "node",
      "args": ["/path/to/mcp-server/dist/mcp/server.js"],
      "env": {
        "INJECTIVE_NETWORK": "mainnet"
      }
    }
  }
}

Set INJECTIVE_NETWORK to "testnet" to use the Injective testnet.

Quickstart

Once connected, a typical session looks like:

> List all BTC and ETH perpetual markets
> What's the current price of BTC?
> Show my balances for inj1...
> Deposit 100 USDT into my trading subaccount
> Open a $50 long on BTC/USDT with 5x leverage
> Show my open positions
> Close my BTC position

For limit orders:

> Open a limit buy on ETH at $3200 for $100 notional, 3x leverage
> List my open limit orders
> Cancel order 0xabc...

For bridging:

> Get a deBridge quote to bridge 50 USDT from Injective to Base
> Bridge 50 USDT to 0x... on Base via deBridge

Security

• Private keys are never stored in plaintext — AES-256-GCM + scrypt at rest
• Keys live in ~/.injective-agent/keys/ with 0600 permissions
• Claude never sees raw private keys — only addresses and tx hashes
• Wallet passwords are passed as tool parameters and may appear in MCP client logs — avoid reusing passwords from other services

See SECURITY.md for the full security model.

Development

npm test                   # unit tests (no network required)
npm run test:integration   # integration tests against testnet
npm run typecheck          # TypeScript type check

Token Support

All Injective denom formats are supported:

| Type | Format | Example | |---|---|---| | Native | inj | INJ | | Peggy (bridged ERC-20) | peggy0x... | USDT | | IBC | ibc/... | ATOM | | TokenFactory | factory/inj.../name | — | | MTS / Injective EVM ERC-20 | erc20:0x... | Injective EVM tokens |

Token metadata (symbol, decimals) is resolved automatically against on-chain registry and cached for the lifetime of the server process.

Networks

| Network | INJECTIVE_NETWORK | |---|---| | Mainnet | mainnet | | Testnet | testnet |
